In addition, the convex design of the first eyeglass object side 12, can also further strengthen first eyeglass 10 Positive refracting power, on the basis of ensureing that the camera optical microscope group has larger field angle, to further reduce the camera shooting The total length of optics microscope group, it is smaller so as to so that the camera optical microscope group, in order to be integrated in such as subsequently On the devices such as electronic equipment.
Second eyeglass 20 is the eyeglass with negative power, to provide negative refracting power, for correcting described first Difference caused by the excessive positive refracting power of eyeglass 10.Second eyeglass 20 has one second eyeglass image side surface 21 and one the Two eyeglass object sides 22, the second eyeglass image side surface 21 is towards the imaging surface 41,22 direction of the second eyeglass object side The first eyeglass image side surface 11, and the second eyeglass object side 22 is concave surface, for correcting the videography optical lens Group Pei Hereby cut down sum number, so that good image quality is obtained at the middle part of second eyeglass 20 and periphery, to have Conducive to the iris camera module for ensureing prepared by the camera optical microscope group, reliability and stability in use.
It is noted that in some embodiments of the invention, according to lens curvature radius, the second eyeglass image side Face 21 is convex surface, and according to eyeglass rise, the second eyeglass image side surface 21 can be convex surface or concave surface, according to eyeglass So that the camera optical microscope group has different performances.
The third eyeglass 30 is the eyeglass with negative power, to provide negative refracting power, wherein the third eyeglass 30 With a third eyeglass image side surface 31 and a third eyeglass object side 32, the third eyeglass image side surface 31 is towards the imaging Face 41, the third eyeglass object side 32 is towards the second eyeglass image side surface 21, and the third eyeglass object side 32 is Concave surface.
It is noted that in some embodiments of the invention, the third eyeglass image side surface 31 is convex surface.
In this embodiment in accordance with the invention, the first eyeglass image side surface 11, the first eyeglass object side 12, described Second eyeglass image side surface 21, the second eyeglass object side 22, the third eyeglass image side surface 31 and the third eyeglass object side At least one side is aspherical in face 32, to meet the need that the iris camera module is prepared by the camera optical microscope group It will.
It is noted that in some embodiments of the invention, first eyeglass 10, second eyeglass 20 and institute The each side for stating third eyeglass 30 can be aspherical, with can be by by first eyeglass 10, second eyeglass 20 are designed to different shapes from the third eyeglass 30, the parameter of the camera optical microscope group is configured, so as to as much as possible Eliminate aberration.
More, the material of first eyeglass 10, second eyeglass 20 and the third eyeglass 30 can be selective Ground selects one kind of plastics or glass.For example, when first eyeglass 10, second eyeglass 20 are selected with the third eyeglass 30 When selecting plastic material and being made, it can cause the camera optical microscope group that there is relatively low manufacture cost, and also be able to reduce it Manufacture difficulty, to further improve product yield；When first eyeglass 10, second eyeglass 20 and the third eyeglass 30 When selection glass material is made, the degree of freedom of the refracting power configuration of the camera optical microscope group can be increased, in the camera shooting When optics microscope group is prepared to the iris camera module, the quality of the image of the iris feature of user is acquired by it is improved.
After the camera optical microscope group is configured, spatial position is stablized, that is to say, that first eyeglass 10, Stablize constant, also, first eyeglass 10, described second in the spatial position of second eyeglass 20 and the third eyeglass 30 There is certain gap, to prevent in the process for assembling the camera optical microscope group between eyeglass 20 and the third eyeglass 30 In, occur situation about colliding between each other.So as to improve the iris camera module prepared by the camera optical microscope group The image clearly of the iris feature of the user of acquisition, to increase the letter of the iris feature of the user of the iris camera module acquisition Breath amount, so as to which subsequently reliably certification can be being carried out to the identity of user.
In the present invention, the first eyeglass object side 12 of first eyeglass 10 to the imaging surface 41 on optical axis away from From for TTL；The focal length of the camera optical microscope group is f, and the focal length of first eyeglass 10 is f1；The institute of first eyeglass 10 The effective radius of the first eyeglass object side 12 is stated as SD11, the third eyeglass image side surface 31 of the third eyeglass 30 it is effective Radius is SD32；The center thickness of first eyeglass 10 is CT1 (the first eyeglass image side surfaces 11 to the first eyeglass object Side 12 is in the distance on optical axis), the center thickness of second eyeglass 20 is CT2 (the second eyeglass image side surfaces 21 to institute The second eyeglass object side 22 is stated in the distance on optical axis)；The f-number of the camera optical microscope group is Fno.
It should be understood by those skilled in the art that in various embodiments, the camera optical microscope group is at least full The condition that foot is stated：
